If you have a website then you already know the importance of traffic. Traffic is to Internet marketing as location is to real estate. It's the only thing that really matters. If you cannot generate targeted visitors to your site, you will not make any sales.
Usually the owner or designer of the website is the person designated to drive traffic to the site. The chief ingredient in generating traffic is the search engine.

Of coarse, you can use advertising, but it's going to cost you. Using the search engines to generate targeted (interested in your product) traffic is the least expensive method known.
Unfortunately, many website owners do not understand the importance of search engine visibility, which leads to traffic. They place more importance on producing a "pretty" website. Not that this is bad, but it is really secondary to search engine placement.

Hopefully, the following list of common mistakes, made by many website owners, will help you generate more targeted traffic to your site.after all, isn't that what you want.
1. Not using keywords effectively.
This is probably one of the most critical area of site design. Choose the right keywords and potential customers will find your site. Use the wrong ones and your site will see little, if any, traffic.
2. Repeating the same keywords.
When you use the same keywords over and over again (called keyword stacking) the search engines may downgrade (or skip) the page or site.

3. Robbing pages from other websites.
How many times have you heard or read that "this is the Internet and it's ok" to steal icons and text from websites to use on your site. Don't do it. Its one thing to learn from others who have been there and another to outright copy their work. The search engines are very smart and usually detect page duplication. They may even prevent you from ever being listed by them.
4. Using keywords that are not related to your website.
Many unethical website owners try to gain search engine visibility by using keywords that have nothing at all to do with their website.

They place unrelated keywords in a page (such as "sex", the name of a known celebrity, the hot search topic of the day, etc.) inside a meta tag for a page. The keyword doesn't have anything to do with the page topic. However, since the keyword is popular, they think this will boost their visibility. This technique is considered spam by the search engines and may cause the page (or sometimes the whole site) to be removed from the search engine listing.
5. Keyword stuffing.
Somewhat like keyword stacking listed above, this means to assign multiple keywords to the description of a graphic or layer that appears on your website by using the "alt=" HTML parameter. If the search engines find that this text does not really describe the graphic or layer it will be considered spam.
6.

Relying on hidden text.
You might be inclined to think that if you cannot see it, it doesn't hurt. Wrong. Do not try to hide your keywords or keyword phrases by making them invisible. For example, some unethical designers my set the keywords to the same color as the background of the web page; thereby, making it invisible.
7. Relying on tiny text.
This is another version of the item above (relying on hidden text).
